MACHINE FOR MAKING CORRUGATED PAPER.

Specification of Letters Patent.

Patented Ang. 11, 1914i.-

Application led May 7, 1913. Serial No. 766,242.

-been mounted close to the corrugated roller over which the paper passes and applies the l,paste to the outermost projecting po-rtion's of the corrugations in the paper, there Abeing only the thickness of the paper be tween the paste applying roll and the corrugated roller with the result that when a torn place in the paper arrives between the paste roll and corrugated roller, paste from the paste roll is applied through the open ing in the paper directly to the corrugated roller,'and this. paste adheres to the roller and is very ditiicult to remove therefrom, and one of the main objects of the present invention is to avoid this difficultyand in the present embodiment I accomplish it by locating the paste roll at a point slightly farther away from vthe corrugated roller and I makeA provision in the paper guides to allow the paper to move a short distance away from the corrugated roller when the paper approaches the paste applying point, so that the paper thus comes in contact with the paste roller and when a. torn place in the paper arrives at the paste roll, the paste `roll being at a distance from the corrugated roller, no paste is applied to the corrugated roller.

Another object is to provide cleanout points arranged adjustably on the scraper bar.

A- further object is to journal the scraper bar in end frames arranged to enable it to be adjusted toward or from the paste roll and adapted to be turned over for cleaning.

Referring to the drawings: Figure 1 isa rear elevation of the machine showing parts broken away. Fig. 2 is a perspective of a paper guide. Fig. 8 is a plan view of a portion of the machine at the scraper points. Fig. 4. is a. vertical section through the machine on line .mL-, Fig. 1. Fig. 5 is an enlarged section on the same plane a.' Fig. 4 of that portion of the machine adjacent to the corrugated rollers and paste roll. i

As the'present invention relates only to the aforementioned features, only a briel description is required of the other portions of the machine.

1 designates the frame in which are revt lubly mounted two corrugation forming rollers 2 and 3, which are driven by gears 4 and' 5.

6 is the paper which is to be corrugated in the machine and applied to a Hat strip of paper 7. The paper 6 passes over an idle roller 8, and thence between the corrugation forming rollers 2 and 3, which act to corrugate the paper 6, as the paper passes through the rollers 2 and 3. paper passes around the inner side of the roller 3 an adhesive is applied to it as will be described, and t-he paper G then passes between roller 3 and a roller 9, over which the plain paper 7 passes, and the corrugated paper 6 is thereby brought into Contact with the paper 7 and its projecting corrugated portions to which the adhesive has been applied are thus secured to the tiat paper 7 so that the two sheets of paper issue from the machine secured together.

10 is an adhesive roller journaled in blocks l1 which are slidable in the frame 1, and is driven by a gear 12, see Fig. 5, the gear 12 meshing with a gear 13, the gears 12 and 13 being of a size which permits the roller 10 to be spaced a slight distance away from the roller 3, as clearly shown in F ig. 5. A series of curved paper guides 14 are arranged between roller 3 and adhesive roll 10, the latter roll having a series of grooves 15 which receive the respective guides 14. Each of the guides 14 has an inner curved vedge 16, which is concentric with the roller 3 and has a cut out portion 17 located at a point to allow the corrugated paper (5 to spring away from the roller 3 and come in contact with the adhesive roll 10, so that adhesive is applied to the paper when the latter passes into and through the cut out portions 17. Each paper guide 14 is pivotally supported by an arm 18, which extends thro-ugh a shaft 1S) and is adjustahly retained in position therein by a. set screw 20. The concentric edges 1G hold the paper against the corrugated roller 3, and the cutaway portions 17 of the paper guides permit the paper tospring away from the corrugated roller at that point, as clearly shown in Fig. 5. and thus move into contact with the adhesive roller 1 0 and receive the applilVhile the.

cation 'of adhesive, afterwhich'thepaper is again caused to travel close against the corrugated roller and be secured against the lat strip of paper 7. By this constructionthe adhesive roller is kept at a distance from the corrugated roller, and thus it is impossible for any adhesive to get on to the corrugated roller. The adhesive roller 10 receives its supply from a trough 21, and in order to keep the grooves 15 cleared out I provide a series of cleanout fingers 22.

These are secured by a set screw' 23 to a scraper 24, the latter acting to clean superluous adhesive fronexthe outer surface of the .adhesive roller 10. -The scraper 24 is carried on brackets 25, which are supported by a rod 26, the rod 26 being supported b end frames 27, each end frame 27 being a justably secured to a stud 28 by nuts 29, the lower end of each stud 28 being pivoted at 3() to a lug 31 on the main frame 1. `This construction is such that byregulating the nuts 29, frames 27 may be swung up or down to rock the shaft 26, and 'thereby swing the Acleanout fingers 22 and scraper 24 away plying means adjacent thereto and out of contact with said conducting means, means for holding the paper in contact with the conducting means at separated areas, whereby the spring Aof the paper between said areas causes the paper to contact with the adhesive applying means.

- 2. In a machine for making corrugated paper, a roller over which the paper is passed, an adhesive roll located out of contact with said roller, and guide means for causing said paper to first contact with said .roller andi-then permit it tospring away therefrom and then cause 1t to contact. with said roller. I

3. In a machine for making corrugated paper, a forming roller over which the paper passes, an adhesive roll located `adjacent to and out of contact with the forming roller, saidA adhesive roller having grooves, a series of paper guides received by said grooves and guiding the paper on "said form* ing roller, said paper guides having cutaway portions to permit the paper to move awa-y from the formingroller into Contact with the adhesive roller. Y y 1 4. In al machine for making 'corrugated paper, a forming roller over which the paper passes, an adhesive roll located adjacent to and out of contact with the forming roller,

said adhesive roll having grooves, a series of paper guides received by said grooves and guiding the paper on said for-ming roller, said paper hesive roll, and means projecting intovsaid uides having cutaway portions' to permit t e paper to spring awayfr'om v the forming roller into contact with .theladgrooves for cleaning the same from adhesive.

5. In a Vmaghine for makingl corrugated paper, a pair ofcorrugated rollers between which the paper is passed, an adhesive roll located opposite one of said corrugated rollers and out of contact with it, .concave guides with recesses for holding the corrugated paper in close contact at separated points with the latter corrugated roller, said recesses guiding the paper in contact with two portions of the corrugated roller, and permitting the paper tospring away from the corrugated rollerat that portion of the roller between said first mentioned portions.

In testimony whereof, I have hereunto set my hand at Los Angeles, California,'this 1st day of May 1913,.v
